How To: Program a $6 NodeMCU to Detect Wi-Fi Jamming Attacks in the Arduino IDE

Hackers and makers are often grouped under the same label. While hackers draw on computer science skills to write programs and find bugs, makers use electrical engineering to create hardware prototypes from microprocessor boards like the Arduino. We'll exercise both sets of skills to program a $6 NodeMCU to display the status of a Wi-Fi link via an LED, allowing us to monitor for jamming attacks.

How To: Use Beginner Python to Build a Brute-Force Tool for SHA-1 Hashes

Developers creating login systems know better than to store passwords in plain text, usually storing hashes of a password to prevent storing the credentials in a way a hacker could steal.

How To: Find the area of triangle using fraction measurement

This video demonstrates the way to find the area of a triangle using fraction measurements. The person presenting this video first writes the actual formula for calculating the area of the triangle. The formula is: the area of the triangle denoted by ‘A’ is equal to half of ‘b’ times ‘h’ where ‘b’ and ‘h’ are the base and height of the triangle, respectively. Now, to make it into fractions, he writes ‘b’ and ‘h’ over ‘1’. Then he asks you to calculate “what is one times ‘b’ times ‘h’” which i...

The first formula to calculate the area of a triangle is area A = (1/2) * a * b * Sin(C), where a and b are the lengths of the two sides of the triangle and C is the value of the angle of the triangle that lies in between the two sides a, b. Now substitute these values in the given formula to find the area if you have...
